Also Known As: H. Pylori Antigen Test, Stool Antigen Test

The Helicobacter pylori Urea Breath Test detects H. pylori infection, a common cause of ulcers and gastritis. After drinking a urea solution, breath samples are analyzed for carbon dioxide changes caused by the bacteria. A positive result indicates active infection, while a negative shows no evidence of H. pylori. Doctors use this noninvasive test to diagnose infection, confirm eradication after treatment, and monitor gastrointestinal health.

The Immunoglobulin E (IgE) Test measures IgE antibody levels in blood to evaluate allergic reactions, asthma, and immune response. Elevated IgE may indicate allergies to food, pollen, or other triggers, as well as eczema or parasitic infections. Doctors order this test to investigate symptoms like hives, sneezing, or wheezing and to guide allergy treatment. Results provide vital insight into immune health, allergic sensitivity, and overall diagnostic care.

Also Known As: Immunoglobulin E Test, Immunoglobulin E Antibody Test, IgE Antibody Test

The Immunoglobulin G (IgG) Test measures IgG antibody levels in blood to assess immune system function and long-term response to infections. Low IgG may indicate immune deficiencies or recurrent infections, while high levels may signal chronic inflammation, autoimmune disease, or certain infections. Doctors use this test to evaluate unexplained illness, monitor immune disorders, or assess overall immunity. Results provide vital insight into immune health and disease management.

: Serum
Also Known As: Immunoglobulin G Test, Immunoglobulin G Antibody Test, IgG Antibody Test

The IgG Subclasses Panel measures the four IgG antibody subclasses (IgG1, IgG2, IgG3, IgG4) in the blood. These antibodies play a key role in immune defense against infections. The test helps evaluate immune system function, detect subclass deficiencies, and investigate recurrent infections or certain immune-related conditions.

: Serum

The Immunoglobulin M (IgM) Test measures IgM antibody levels in blood to evaluate immune response and early defense against infections. High IgM may indicate recent or acute infections, autoimmune disease, or certain blood disorders, while low levels may suggest immune deficiency. Doctors order this test to investigate recurrent infections, unexplained inflammation, or suspected immune problems. Results provide vital insight into antibody health, immune status, and diagnostic care.

The Immunoglobulin A (IgA) Test measures IgA antibody levels in blood to evaluate immune system health and mucosal defense in the respiratory and digestive tracts. Low IgA may indicate immune deficiency, celiac disease, or recurrent infections, while high levels may suggest autoimmune disorders, liver disease, or chronic inflammation. Doctors use this test to assess unexplained illness or immune imbalance. Results provide key insight into antibody function and overall immunity.

 The Indican Urine Test, also known as the Obermeyer Test, measures the amount of indican in the urine. Indican (indoxyl sulfate) is a colorless compound that is formed when the amino acid tryptophan gets broken down by bacteria in the intestine. Once formed, indican travels to the liver, where it's typically converted into indoxyl and then excreted in the urine. High levels of indican in the urine can suggest an increased amount of protein decomposition in the gut or problems with normal digestion and absorption.
